IM PROVEMENT IN WINDEVI ILLS.

Specification forming part of Letters Patent No. lib-3,728, dated July31, 1877; application filed April 21, 1877. v

To all whom it may concern:

Be it known that I, SAMUEL RITTENHOUSE, of Pioneer, in the county ofWilliams and State of Ohio, have invented certain new and usefulImprovements in Windmills; and I do hereby declare that the following isa full, clear, and exact description thereof, which will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, which form a part ofthis specification, and in which- Figure 1 is a perspective view, andFig. 2 is a side elevation.

Similar letters of reference indicate corresponding parts in both thefigures.

This invention relates to windmills, such as are used for pumping water;and it consists, first, in the arrangement of a supplementary vane,which shall be in operation in high wind only, and the effect of whichshall be to regulate the position of the main vane, and that of thewheel, in such a manner that the motion of the wheel shall be no fasterin spite of the increased force of the wind; and, secondly, in thearrangement in the water-tank of a board pivoted to a lever, the otherend of which is connected by a chain to the supplementary vane, and theresult of which is, when the tank is full of water, to throw thesupplementary vane into and the main vane out of gear, to such a degreeas to cause the wheel to be set at an angle to the wind, and thusslackening its speed until the water in the tank runs low, when thevanes and wheel are automatically reset in their former position.

In the drawing, A is the frame of my improved windmill. This hasbearings b b, for the crank-shaft a. of the windwheel. The frame A ispivoted upon a cylinder, 0, secured on top of the main post or standardI). c is the sucker-rod, which passes through cylinder 0. Its upper endis connected, as shown, to the crank of shaft a, by which it isoperated.

F is the main vane, which is hinged in the usual manner to the side offrame A. To the front of frame A, upon the side farthest from vane F, ishinged another supplementary vane, G. The hinge of vane G is horizontal,so that the vane instead of moving sidewise is moved up and down, andthe vane itself is set at. an angle, so as to present buta very smallsurface to the wind.

The vane G is connected by a rod, 01,. with the vane F, the result ofwhichis when vane Gr is thrown up by the wind to the position shown indotted lines, Fig. 1, to carry the vane F with it, as also shown indotted lines, thus placing it at a right angle, or nearly so, to theframe A, and causing the wheel to be placed in such a position as toexpose but a small surface to the wind, thus slackening its speed. Thevane F is provided witha shoulder, '0, which, by resting against theframe A, prevents it from being thrown too far out of gear.

H is a lever, which is pivoted to the side of post D slightly above thewater-tankf. To one end of this lever is hinged a board, 9, coveringabout one-half of the tank, inside of which it slides, and to its otherend is secured a chain or rope, h, which passes through cylinder 0, upover a pulley, t, upon frame A, and down to the vane G, to which it issecured at j.

Whenever the tank is filling up with water, and is in danger of runningover, the board 9 is raised by the pressure of the water, thus loweringthe opposite end of lever H. This, being connected by chain It to vaneG, raises this latter, thus throwing the vane F, and, consequently, thewind-wheel, out of gear. When the Water-level in' the tank is lowered,the vane G will gradually and automatically return to its formerposition, thus gradually increasing the speed of the wheel.

K is a bracket or rod, secured to the frame A under vane G, to serve asa rest for this latter, and prevent it from coming down too far.

The operation and advantages of my invention will be readily understoodfrom the foregoing description. The vane G serves to automaticallyregulate the speed of the wheel. Owing to the method of hingingit-horizontallyto frame A, and to its construction, which exposes aslanting surface to the wind, it cannot be influenced except by a verystrong wind, when it is raised up with the 'result already described. Inan ordinarybreeze it can only be operated by the lever B and chain h inthe manner described, its result thus being to prevent the water-tankfrom overflowmg.

Having thus described my invention, I claim and desire to secure byLetters Patent of the United States- 1. In a windmill, the supplementaryvane G, hinged horizontally, andset slantingly to the frame A,substantially as and for the purpose herein shown and specified.

2. In a windmill, the combination of the pivoted frameA, vane F,supplementary vane G, hinged horizontally, and set slantingly to frameA, and connecting-rod 01, substantially as and for the purpose shown andspecified.

3. In a windmill, having the supplementary horizontally-hinged vane G,the rod or bracket K, serving as a support for the vane G when at rest,substantially as and for the purpose set forth.

4. The combination of the post or standard D, lever H, board g slidingin the water-tank f, chain h, and vane Gr hinged horizontally to theframe A, all arranged to operate substantially in the manner and for thepurpose herein shown and specified.

5. The improved windmill herein described, consisting essentially of thestandard D, pivoted frame A having vanes F G, connected by rod d, tankf,lever H having hinged board 9, chain h, and bracket K, all combined andarranged to operate substantially in the manner and for the purposeherein shown and specified.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses.

SAMUEL RITTENHOUSE.
